SASH HOLDER AND FRAME.

SPECIFICATION forming part of Letters Patent No. 260,213, dated June 27,1882. Application filed October 27, 1881. (No model.)

To all whom it may concern:

Be it known that I, CASPER LOEWENSTEIN, of Columbus, in the county ofFranklin and State of Ohio, have invented a new and useful Improvementin Sash Holders and Frames, of which the following is a full, clear, andexact description.

The object of my invention is such construction of the window-sash andwindow-frame that the sash will be held at any point in the framewithout the use of weights and pulleys or similar expensivecontrivances.

My invention consists in making the vertical side bars of the sashslightly diagonal from the bottom outwardly, or keystone-shaped, andproviding the walls of the frame with bars, which are pressed outwardlyby suitable springs against the diagonal edges of the side bars of thesash, the springs being arranged preferably so as to exert the greatestpressure belowthe longitudinal center of the said springbars.

My invention also consists in the details or construction, ashereinafter more fully described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is an elevation of my improved sash and frame, part of theframe being broken away to better show the construction. Fig. 2 is ahorizontal section of the same, taken on the line a m of Fig. 1; andFig. 3 is a detailed view, showing a modification.

The sash A is made keystone shapedthat is, the vertical side bars a athereof are made wider at the top than at the bottom, as clearly shownin Fig. 1. The walls of the 40 jamb or frame of the window are recessed,as

shown at c c, and in these recesses are placed the vertical bars D D,which extend the whole length of the jamh or frame. In the back or theserecesses are formed the holes d 01, below the longitudinal center of theframe, and also the holes at above said center, and in each of saidholes are placed the coiled springs e, which serve to press the bars D Doutward the frame may be provided with similar stops;

or other means may be employed for keeping the bars in place when thesash is removed. Thus constructed, it will be understood that uponraising the window-sash the sash will be automatically held at any pointin the frame by the force of the springs and the shape of the sash; andit will be understood that a tight joint will always be maintainedbetween the frame and the sash.

In case the sash is very large and heavy, the edges of the side bars ofthe sash will be provided with the points g g, as shown in Fig.

3, which will engage with the spring-bars,

and securely hold the sash at any pointin the frame.

Upon the face of the side bars a a of the.

sash are secured the stops 1' t, which runagainst the inner edges of thejambs of the window-frame, and serve to keep the sash at all timescentered in the frame, and prevent the sash being forced to one side outof position should one set of springs happen to be of greater force thanthe other.

I am aware that pulleys and weights have been dispensed with and pulleystiles rcplaced by four yielding pressure-strips, which actindependently of catch or fastening; also, that it is not new to useyielding friction-strips in the casing to bear against the edges ofsash, said strips being supported in the rear by springs; but

What I claim as new and of my invention 1s- 1. The keystone-shaped sashA, in combination with the spring-supported side bars D D, substantiallyas and for the purposes set forth.

2. In combination with a keystone-shaped sash, the spring bars D D,arranged to exert the greater pressure below their longitudinal centers,substantially as and for the purposes set forth.

3. The bars D D and the springs 0, in com- 5 bina-tion with thekeystone-shaped sash, substantially as and for the purposes set forth.

4. The keystone-shaped sash A, provided with the stops i z, adapted torun against the edge of the jainbs of the window-frame, in combinationwith the spring-supported bars 10 D 1), substantially as and for thepurposes set forth.
